I'm really sorry. I didn't mean to mislead anyone, I just saw this over the weekend, thought it was an amazing deal and posted the link without paying attention to whether it was in or out of stock!
Rokuten is a newer, smaller Alibaba. They bought out the original Buy.com company a few years ago. From what I understand, most of the vape gear on there is from so called "marketplace sellers" a la Amazon, EBay, even Best Buy , Sears, and Walmart are doing that online these days. These are sellers they have absolutely no control over. A big hint for me was all of it is under the category of smoking cessation which while true in anecdotal terms is not valid In current US legal terms, so in short, I don't think they have any input at all over what's delivered or not unless someone complains.
Most of these places including newegg which also carries some starter kits will have the option for the shopping site itself or whoever else sells through them. That was how I was able to track down the vendor who had the best deal going on the Nautilus tanks. The returns and other things go through the shopping site when sold by them while the rest is between you and the seller in most cases. Generally the seller will work with you a bit faster when the shopping site is set up similarly to how EBay's policies work once you have contacted the seller.
Check it again. They appear in stock now.
I'm not surprised to hear that at all since the iStick as well as accessories are flying off of the vendor shelves since all this is still brand new. Once the holidays are over however I think you will start to see things slow down quite a bit since all the deals will be over.
Oh lord why would you wanna do that?

Seriously though, you can chop it up if you so desire but f you must expose the fire button I'd suggest using a razor blade or exacto - something small cause the square is not big at all. A knife may destroy the case completely.

According to Sweet-Vapes they have them in stock now.
Eleaf iStick Leather Case. Price is $9.95 though. I bought 2 for that price when Discount Vapers initially got them in stock. If you don't feel like waiting at least Sweet-Vapes has them.
NASTY IDEA! Generally when you hack something up you end up ruining it in some fashion and end up defeating the purpose. I put one iStick in the MVP/VTR belt holster to see if how that would or wouldn't and the answer was wouldn't work as a substitute while I did make some other interesting observations in the process of seeing what else besides the Eleaf accessory there could work.
Now remember some don't like the Nautilus Mini either complaining about taste or capacity. I added that into the equation when sizing things up a bit. The first is what else is commonly seen in use for carrying even Vamos without tanks attached or other small items.
While that's all nice and roomy for one iStick as well as the 510/ego adapter and beauty ring for the medium not large eGo carrying case. Then I wanted to see about carrying both iSticks at the same time and ...
Gee nice and snug fit with both having tanks on them as you would expect on a longer eGo type battery. The next thing of course was in regards to the comparison of tanks as far as how well they fold over with the Bending Adapter as well as what offers the largest capacity in a small size. Note of course some tank coils won't nandle the full 20w the mod puts out.
That was the Smok Tumbler shown previously on the right with the Nautilus Mini even still not able to fold down as far. Capacity Mini vs Tumbler equaled 2ml for Mini versus 3+ml you can get into a Tumbler. Disadvantage of Tumbler max 10-12w with 2ohm Smok coil in use. Unsure about how much 2.4ohm or 1.8ohm coils will handle since those were never intended for higher wattages.
And lastly the tumbler now on the left is place up against the full size 5ml Nautilus that has been run upwards of 35w on otther APVs but a bit awkward for carrying around in the small watch/coin pocket while out on the go. At 10w however the Tumbler would be just the right size for the iStick Mini however since the max on that is 10w when giving that some food for thought. At 7w-10w the Tumblers have an excellent flavor and vapor output as seen on other lower powered Vamo and VV/VW batteries.
For the Nautilus Mini tanks I like the stainless replacements while the full size lacks the view slot for seeing how much is left in the larger tank! That was is one disappointment seen with Aspire there. So far no bad taste detected from the Mini tank either suggesting if the wattage is up too far with some flavors you will get a hot burnt metal type taste since the flavor is best off left at a reduced output. I run into this with various flavors by just one vendor where I can push 40-50w with some and others not much more then 20w!
